Cannot store Model into Server

Hi,

I'm running a Sentiment Analysis process and when a try to store the model (running in the server) I get the following error.

Capturar.PNG

 

I have also enclosed the log file for the error.

I sucessfully  saved the model in the local repository, but when I try to copy/paste into the Server folder I get the same 500 error.

 

Regards

 

Michel

    This error typically relates to not being able to save the model file to the Server or there is a problem in the backend database. The model is stored in a table in the backend database and somethings things like encoding and packet size on the database side can cause problems.

    I have the same issue.

    It happens on the Server version but also on the Studio version - albeit randomly it seems.

     

    Here is a log of the issue on the Server side :

     Also, interestingly :

    I thought I could circumvent the issue by using the "Write Model" operator instead of the "Store" operator.

    It is not the case unfortunately. The Write Model operator triggers another Stack Overflow error (The file size grows out of proportion and it ultimately crashes).

     

    For the sake of clarity, I'm posting to this thread because I tried to copy a working backup of the model into the server and it triggered the same error (unable to upload the model to the server).

    Alright, more info coming out of a fresh log.

    • The crash happens on a javax.ejb.EJBException: JBA014580: Unexpected Error
    • Caused by a java.lang.StackOverflowError
    • It looks like something is wrong with the IOObjectVersion on some RepositoryEJBImpl

    Hope this can help
